Paramagnetic metal complexes with TTF moieties in their ligands were newly synthesized; TTF denotes tetrathiafulvalene and its derivatives are well known as the component molecules for molecular conductors. Crystal structures and physical properties including electrical conductivity of the TTF-based metal complexes were investigated. We succeeded in the development of thin layer film of Cu(II) complex by the vacuum evaporation process and the fabrication of its FET device. Because the FET properties were not observed in the device of the Cu(II) complex, we modified the TTF based metal complex in order to apply the wet process for device construction. We prepared a new metal complex having self-assembling ability; the cubic metal complex with long alkyl chains attached to the TTF ligands exhibited gelation for some organic solevents.
